Speculative Multithreading Architectures
Multiprocessor system evaluation has traditionally been based on direct-execution based Execution-Driven Simulations (EDS) where the processor component of the system is not fully modeled. However, using direct-execution to model a superscalar processor has been considered an open problem. In the …

In-core, hint-based, speculative multithreading
… Thread-level speculation (TLS or SpMT, speculative multi-threading) has been identified as a possible solution in past academic work, but there has been a large disconnect between academia and industry in identifying design constraints and addressing practical adoption hurdles, which has …

Chip Multiprocessors With Speculative Multithreading: Design for Performance and Energy Efficiency
Experiments with the SpecInt 2000 codes show that a CMP with 4 3-issue cores and support for SM delivers a speedup of 1.27 over a 3-issue superscalar. The SM CMP is even faster than a 6-issue superscalar at the same frequency, and consumes only 85% of its power. In fact, for the same average power …
